WHILE DEPRESSING THE BRAKE PEDAL IN THE 2010 PRIUS, THE VEHICLE WILL LOSE ALL BRAKING POWER IF YOU HIT A BUMP OR POT HOLE IN THE ROAD. I HAVE EXPERIENCED THIS SEVERAL TIMES WHILE DEPRESSING THE BRAKE, APPROACHING AN INTERSECTION. WHEN I DRIVE OVER THE BUMP IN THE ROAD (AND CONTINUE PRESSING THE BRAKE) THE VEHICLE SURGES FORWARD AS IF MY FOOT HAD RELEASED THE BRAKE. THE ONLY WAY TO STOP THE VEHICLE IS TO IMMEDIATELY RE-ENGAGE THE BRAKE FULLY. I HAVE CAME VERY CLOSE TO REAR ENDING THE VEHICLE IN FRONT OF ME DUE TO THIS DESIGN / MECHANICAL FLAW. I CAN RECREATE THIS SCENARIO EACH TIME I CROSS A CERTAIN PORTION OF THE ROAD I COMMUTE ON. *TR

WHEN BRAKING NUMEROUS TIMES, MY 2010 TOYOTA PRIUS HAS STOPPED BRAKING AND GIVES THE FEELING THAT IT IS LURCHING FORWARD. MY MOST RECENT INCIDENT OCCURRED WHEN I WAS DRIVING OVER A MAN HOLE AT ABOUT 30-35 MPH. THESE INCIDENTS TYPICALLY OCCUR WHEN BRAKING OVER NON-SMOOTH ROAD SURFACES, SUCH AS POTHOLES. I HAVE OWNED THE CAR SINCE JUNE 2009. *TR

I HAVE A 2010 PRIUS. I HAVE NOTICED A PROBLEM WITH THE BRAKING IN CERTAIN CONDITIONS AS DESCRIBED: WHEN THE PRIUS HITS A PATCH OF UNEVEN PAVEMENT OR IS TAKING A SHARP TURN WHILE LIGHTLY BRAKING, THE PRIUS' BRAKE ECU INTERPRETS THAT AS A SITUATION WHERE THE COMPUTER NEEDS TO STEP IN AND KEEP THE WHEELS FROM LOCKING UP. THE BRAKES DO END UP WORKING BUT IT IS AN UNSETTLING AND DEFINITELY A POTENTIAL DANGEROUS SITUATION AS THERE IS A SURGE PRIOR TO THE BREAKS ACTUALLY WORKING. THE SURGE ONLY LASTS A SECOND OR SO BUT IT DOES FEEL LIKE THE CAR IS ACTUALLY ACCELERATING AND NOT BRAKING FOR THAT BRIEF MOMENT. *TR

WHEN ATTEMPTING TO BRAKE WHILE COMING TO A TRAFFIC LIGHT ON A SLIGHTLY ICY ROAD, THE CAR ACCELERATED. IT WAS NOT THE FUNCTION OF ANTILOCK BRAKES, BUT RATHER A SURGE THAT WAS TOTALLY UNEXPECTED AND SOMEWHAT FRIGHTENING. LUCKILY THERE WAS NO CAR IMMEDIATELY IN FRONT OF ME, OR I WOULD HAVE SURELY REAR ENDED IT. I REPORTED THIS TO TOYOTA AND THERE IS A CASE NUMBER - 1001142944. GIVEN TOYOTA'S SLOWNESS TO REACT TO THE GAS PEDAL ISSUE, I WANT TO NOTIFY NHTSA. *TR

MY 2010 TOYOTA PRIUS SUDDENLY SURGED FORWARD FOR A FEW FEET AFTER GOING OVER A LITTLE BUMP IN THE ROAD (LIKE A MANHOLE COVER). THIS HAPPENED A COUPLE OF TIMES. NO INJURIES OR ACCIDENTS. I BROUGHT THIS TO THE ATTENTION OF MY DEALER WHEN I BROUGHT IT IN TO CHANGE THE OIL @ 5000 MILES. THEY SAID THEY COULD NOT REPLICATE OR DETECT THE PROBLEM. I HAVE NOT HAD ANY SUCH INCIDENTS IN THE PAST 2 MONTHS. *TR

MY 2010 TOYOTA PRIUS EXPERIENCES ACCELERATION WHENEVER I GO OVER A POTHOLE AND ATTEMPT TO BRAKE THE CAR. THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE IN AUGUST 2009. I AM REPORTING IT NOW BECAUSE I NOW KNOW THAT OTHER OWNERS HAVE REPORTED THE SAME PROBLEM AND IT IS NOT A RESULT OF MY INABILITY TO GET USED TO DRIVING A HYBRID. THIS IS A SERIOUS SAFETY ISSUE AS I'M ALARMED THAT I MAY BE UNABLE TO BRAKE SUDDENLY IF THIS HAPPENS IN A SITUATION THAT WARRANTS ME TO QUICKLY BRAKE. *TR

MY 2010 PRIUS HAS BRAKES RELEASING WHILE MY FOOT IS ON THE BRAKE PEDAL. IN REVERSE THE BRAKES FREQUENTLY "STICK" ON. IN THIS MOST RECENT INCIDENT I WAS CHANGING LANES LOOKING TO MAKE A FUTURE LEFT TURN AND I WAS IN THE RIGHT LANE OF A 4 LANE ROAD, I WAS SLOWING DOWN TO CHANGE LANES AND DID NOT SEE A CAR IN MY "BLIND SPOT" WHERE MY MIRRORS DID NOT SHOW THE CAR. ONCE I SIDE SWIPED THE ACURA MDX, I MADE EMERGENCY MANEUVERS TO GET BACK TO THE RIGHT LANE, WHICH INCLUDED SWERVING RIGHT AND HITTING THE BRAKES AFTER THE CAR STARTED MOVING RIGHT. AT THAT POINT MY VEHICLE SEEMED TO MOVE ON IT'S OWN IRREGARDLESS OF MY PEDAL AND STEERING ACTIONS (I WAS IN PANIC MODE SINCE I HAVEN'T HAD AN ACCIDENT IN DECADES - EXCEPT A PARKING LOT "BUMP"). I WROTE OFF THE FACT THAT I WAS UNABLE TO DEFENSIVELY DRIVE AS I HAVE RELIED ON FOR ALL THESE YEARS SINCE I COULDN'T PULL OUT OF THE ACCIDENT. NOW HOWEVER, AFTER HEARING OF THE SIMILAR ISSUES ON 2010 PRIUS I AM WONDERING WHETHER THE VEHICLE PLAYED A PART IN THE ACCIDENT THAT I COULD NOT COMPENSATE FOR? *TR

PARKING BRAKE
I BOUGHT A 2010 TOYOTA PRIUS II NOVEMBER 2009. WITHIN 1 MONTH PERIOD, I HAD EXPERIENCE TWO SEPARATE BRAKE PROBLEM. ONCE WAS PASSING A RAILWAY TRACK AND THE OTHER TIME WAS MAKING A RIGHT TURN. BOTH TIMES I STEPPED THE BRAKE TO REDUCE SPEED AND FAILED. THAT MEANS THE BRAKE DID NOT REDUCE THE SPEED OF THE VEHICLE. FORTUNATELY, NO CAR WAS IN FRONT ME AND NO ACCIDENT HAPPENED. I THEN REPORTED TO MY DEALER AND SENT MY CAR BACK TO CHECK. THE DEALER TOLD ME THEY FAILED TO REPLICATE THE SITUATION AND EVERYTHING WAS NORMAL. NOTHING WAS DONE. THEY THEN TALKED TO TOYOTA CUSTOMER SERVICE LINE AND TOYOTA SAID IT IS NORMAL TO FEEL THE BRAKE DID NOT ENGAGE WHEN CROSSING A BUMP. I WAS REALLY DISAPPOINTED. *TR
